OONCBME WALL CONSTRUCTION.

Application fled um 10, 1024. mm Io. 708,800.

To allwhom it may concern:

Be it known that I, HARRY E. CLoUsER, a citizen of the United States,residing at San Jose, county of Santa Clara, State of California, haveinvented certain new and useful Improvements in Concrete WallConstruction; and I do declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawin s, and to the characters of reference mar ed thereon, which forma part of this application.

This invention relates to improvements in the construction of wallsbuilt up of concrete blocks interlocked with each other against relativelateral and longitudinal movement, such as are shown for instance inPatent No. 1,374,356 dated April 12th, 1921, and Patent No. 1,465,421dated August 21st, 1923.

It is a simple matter to interlock or tie the blocks in each walltogether, and to arran the blocks so that the blocks of each horizontalrow of the wall are in centrally oflset relation, in a longitudinalplane, to the blocks of adjacent rows. To similarly tie two right angledwalls together at their ends, or in other words at a corner, presentshowever a different problem.

The principal object of my present invention therefore is to producecooperating corner block construction of sim le form, using only asingle special form 0 block, so constructed and arranged with respect tothe main blocks of the two walls, that said walls will be positivelyinterlocked from top to bottom, said corner blocks being arranged to bedisposed in staggered vertical alinement so that no continuous jointline between the blocks is had, thus providing a very strong cornerconstruction.

Another object is to pro ortion the length of these corner blocks reative to that of the main wall blocks in such a manner that thecentrally offset ,alinement of the main blocks of different rows, asabove specified,

is not interfered with.

These corner blocks are also made flat, avoiding the useof right angledcorner blocks as shown in Patent No. 1,374,356 g: entioned above, whichblocks are relatively to make, and are hard to stack for' abi ment orstorage.

wall constructed with my resent form of block can be readily set up withunskilled labor without danger of the workers making vmlstakes in ihelaying of the blocks, so that building operations are very inexpensive.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicated correspondingparts in the several views:

Fig. 1 is a perspective view of a wallcorner built with my improved formof corner blocks.

Figs. 2 and 3 are perspective views of cooperating corner blocks ofadjacent rows, positioned in spaced relation to show the interlockingfeatures.

' Fig. 4 is a sectional plan of the blocks at a corner.

Referring now more particularly to the characters of reference marked onthe drawings, the numeral 1 denotes the special block used in my cornerconstruction, only this one block being any diflerent in form or sizefrom the main wall blocks 2, while the height of all said blocks is thesame.

In one course or row A, a block 1 over laps and abuts against a block 2at one end of the later to form a right angle corner therewith, so thatthe outer face of the block 1 and the corresponding end edge of theblock 2 are in alinement.

The end faces of the block 2, and of all the other main blocks, aregrooved as at 3 at one end and tongued as at 4 at the other, so that thevarious main blocks in a course will be tied together against lateraldeflection. Said block 2 is alined with respect to the block 1 so thatthe groove 3 in the former is adjacent the block 1, thereby providingample space between the two blocks for the necessar bonding materialsuch as cement or the li e, while allowing them to have a close fitagainst each other.

The end face of the special block 1 farthest from the corner is groovedas at 5 to receive the ton e 4 of an ordinary main block 2 abuttedthereagainst in alinement therewith, this main block being of coursefollowed by others of the same kind until another corner is reached. Thelen h of the special block 1 is equal to half the length of a main blockplus the thickness of the latter, for the purpose as will hereinafterappear.

The upper faces of the main blocks 2 are longitudinally grooved in acertain spaced manner, as shown at 6, and similarly tongued as at 6" ontheir lower faces. The upper faces of the blocks 1 are similarly groovedas at 7 from their ends alined with the main blocks to' a point inalinement with the inner face of the block 2 which makes the corner withsaid block 1. An additional short groove or socket 8 is formed in theblock 1 at right angles to the grooves 7 and in alinement with thegroove 6 in the abutted corner forming block 1, as shown in Fig. 3.

In the course of blocks B above that just,

described, the position of the corner blocks 1 relative to that of therow below is reversed. In other words, the block 1 of course B is placedat right angles to the block 1 in course A below and extends to theouter side face of said lower course block 1, as shown in Fig. 1,resting both on said lower course block 1 and on the adjacent block 2and alined with the latter. The adjacent corner block 2 of course Babuts against the inner face of the corresponding block 1 and rests bothon the block 1 in course A and on the block 2 in said course alined withthe block 1 thereof.

The corner blocks 1 being all of the definite length hereinbeforespecified, the main or common length blocks-abutted there against in theparticular manner set forth, will overlap each other for exactl halftheir length, as will it is thought be evident without furtherexplanation.

In this manner, the other main blocks of each course, throughout theextent of the wall, will also be maintained in a central offsetstaggered relation to the blocks of ad jacent courses.

To cause the corner blocks 1 of adjacent courses to be interlocked witheach other, the under or bottom faces of each block 1 is tongued as at 9to cooperate with the corresponding portions of the grooves 6 of theblock 2 on which said block 1 rests. Said block 1 has also an additionalshort tongue or knob 10, alined with but spaced from the tongues 9 (seeFig. 2) which knob is positioned to seat in the recess 8 of the block 1below.

The main cooperating tongue and groove members of the different blocksbeing so arranged that no longitudinal movement between the blocks in awall can be had, and the additional end cooperating knobs and recesseson the blocks 1 forming a positive lock between said blocks, the twowalls are securely held together and no parting of said walls at thecorner line can take place.

In a succeeding course, the block 1 thereof would be parallel to andpositioned the same as the block 1 in the first row, and so on inalternate or staggered arrangement from top to bottom of the wall, allthe corner blocks 1 being locked to each other both at top and bottom,thereby making a very strong corner.

From the foregoing description it will be readily seen that I haveproduced such a device as substantiall fulfills the objects of theinvention as set orth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent is:
